摘　　要：建立了测定卷烟侧流烟气中铬（Cr）、镍（Ni）、砷（As）、硒（Se）、镉（Cd）和铅（Pb）6种元素的电感耦合等离子体质谱（ICP-MS）方法。采用鱼尾罩串联石英纤维滤片捕集侧流烟气粒相物,3级硝酸溶液吸收瓶捕集侧流烟气气相物,微波消解法处理样品,ICP-MS法测定。结果表明：6种元素的线性相关系数均在0.999以上,检出限为0.3～1.8 ng/支,加标回收率为94.0%～109.5%。该方法灵敏度和准确度高,适用于侧流烟气中重金属元素的快速测定。A method for determining six heavy metal elements, Cr, Ni, As, Se, Cd and Pb, in sidestream cigarette smoke（SCS） was developed by inductively coupled plasma mass spectrometry（ICP-MS）. The particulate matter in SCS was collected by a＂fishtail＂chimney connected with a quartz fiber filter pad, and the gas phase in SCS was trapped by three cascade impingers containing nitric acid, then subjected to microwave digestion, and determined by ICP-MS. The results showed that the correlation coefficients of the calibration curves of the six elements were all above 0.999, and the detection limits ranged from 0.3 to 1.8 ng/cig with the recoveries of 94.0%-109.5%. This method is accurate, sensitive and suitable for the rapid determination of the said heavy metal elements in SCS.
